About this item

The Corbin Russwin ML2057 NSA is a Grade 1 storeroom mortise lock from the ML2000 series. The model code breaks down as ML = mortise lock, 2057 = storeroom function (ANSI F07), N = Newport lever, S = sectional escutcheon, A = A rose trim configuration. If you've been searching "ml2057", "corbin russwin ml2057", or "corbin ml2057"this is the product. The ML2000 series is Corbin Russwin's standard Grade 1 mortise platform and the ML2057 is the storeroom/closet function in that family.

 

ANSI F07 Storeroom Function: What Happens at the Door

 

The ML2057 is ANSI function F07storeroom/closet. That means the outside lever is always rigid. It won't turn. Turning the outside lever without a key does nothing. The only way to retract the latch from outside is with a key in the outside cylinder. From inside, the lever is always freeanyone inside can grip the lever and exit immediately at any time without a key.

 

The auxiliary latch deadlocks the latchbolt as soon as the door closes. When the door is in the frame with the auxiliary latch depressed, the latchbolt can't be shimmed or pushed back. You need a key from outside to get in. That's the standard access control configuration for storerooms, medication rooms, server rooms, equipment rooms, and any space where unsupervised public access isn't permitted.

 

NSA Trim Configuration: Newport Lever and A Rose

 

The NS in this model means Newport lever in a sectional escutcheon format. The A at the end is the A rose, which is the standard round rose/escutcheon that surrounds the lever on the door face. The Newport lever is a straight horizontal design that meets ADA accessibility requirementsit operates without pinching, grasping, or twisting, and returns to within the required clearance of the door face.

 

If you've been searching "corbin russwin ml2057 ll 626"LL indicates lever/lever trim on both sides, and 626 is Satin Chrome. The ML2057 NSA 626 is the Satin Chrome finish configuration of this lock.

 

ML2057 vs ML2010: Understanding the Sibling Functions

 

The ML2010 appearing in this page's search data is a different ML2000 series functionML2010 is the passage function (ANSI F01), where both levers are always free and there's no locking. The ML2057 is the storeroom version where outside access requires a key. Both use the same lockcase platform, so if your project has a mix of passage and storeroom doors, the ML2000 series handles both within a single hardware schedule.
